MOTOR-VEHICLE..

SPECIFICATION forming part of Letters Patent No. 778,810, dated December27. 1904.

Application filed May 12,1904. Serial No. 207,629.

To f//Z 7072/0111/ 1715 party concern:

Be it known that we,TI-roMAs LEGGETT STUP.- TEVANT. residing at Quincy,and THoMAs J. S'rURTEv.-\N'r, residing at lVellesley, in the county ofNorfolk and State of Massachusetts, citizens of the United States, haveinvented certain new and useful Improvements in Motor-Vehicles orAutomobiles, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to automobiles or motor-vehicles, and has for itsobject to provide such a construction and arrangement of parts enteringinto or mounted on the chassis or running-gear of the vehicle as willcombine the greatest convenience with the highest efliciency, both withreference to the machine when in use as also with regard to conveniencein assembling or dismounting parts of the engine.

ln the accompanying drawings, Figure 1 is a side view of the forwardpart of the chassis or running-gear of an automobile involving thepresent invention. Fig. 2 is a plan view of the same. Fig. 3 is a sideview of the engine, showing the manner of supporting the same on theside bars of the vehicle which are represented in cross-section, thelower valvecasing shown in Fig. 2 being' omitted from Fig. l). Figs. 4and 5 are detail end views illustrating modified forms ofengine-cylinders and the manner ofmounting the same.

Referring to the drawings, 12 denotes the side bars or side beams of thechassis or running-gear frame of the vehicle and which, as will be seenfrom Fig. 2, are bent toward each other in forming the forward part ofthe vehicle-frame for the purpose of giving a better clearance for theforward wheels 13 of the vehicle, to enable sharp turns to be made, asalso for the purpose of so mounting a transversely-arrangedopposed-cylinder engine in such a manner that the cylinder portions ofthe engin e-frame will project laterally on each side of thevehicle-frame a sufiicient distance to permit of ready access to thevalve mechanisms and sparking' plugs of the engine for the purpose ofadjustment or repairs.

The vehicle herein shown is provided with an explosion or gas engine,although the invention is not to be understood as being limited to anyparticular form of engine.

The engine-frame herein shown comprises a crank-case la, to the oppositeends of which are attached, by bolts and nuts 15, the cylinder-casings16, which are secured beneath the side bars 1Q of the vehicle-frame bybolts and nuts 17. The engine frame or case as a whole thus constitutesa cross-bar which will brace and strengthen the forward part of thevehicle-frame transversely, and the location ot' the engine-framebeneath the Vehicle-frame locates the weight of the engine low down onthe vehicle, so as to afford a low center of gravity, and therebycontributes to the steadiness ot' the vehicle when in motion. Owing tothe construction and arrangement otl parts just described, acylinder-casing 16 at either end of the engine may readily be dismounted1 for cleaning or repairs without disturbing the cylinder-casing at theother end of the engine, it only being necessary when a singleunitcylinder-casing at one end of the engine is to be removed to properlyblock up the crank-casing and then loosen the cylindercasing from itssupports on the crank-casing and the vehicle-frame.

1n the form of the invention shown in Figs. 1 and 2 eachcylinder-casingl 16 is a double one, comprising two of the cylinders ofa fourcylinder engine; but for many reasons it may be better to make thecasing for each cylinder separate from or independent of the casing ofthe other cylinder or cylinders.

Fig. l represents the cylinder-casings 16L of a six-cylinder engine asbeing made separate from each other and separately bolted to a side barof the vehicle-frame and to the crank-casing of the engine, while Fig. 5represents a single cylinder 16b of a two-cylinder engine to be boltedto the crank-casing of the engine-frame and to a side bar of thevehicleframe.

In either of the forms of the invention shown each cylinder-casing,whether single or double, forms a cylinder-casing' unit indel pendentlyattachable or dismountable.

Bolted to the side bars 12 of the vehicleframe, rearward of theengine-frame, is a cross-bar 18, which supports the change-gear box orcasing 1S), and between the said changgear box and the engine-frame, onthe enginesha'l't 20,' which runs lengthwise of the mal chine. is afly-wheel 2l, within which is inclosed a centrifugal clutchpower-transitiitting device wlnch will preferably be of the constructionfully shown and described in our United States application, Serial `\'o.187,822,

The vehicle is provided with a starting' shaft 22, provided at the frontof the vehicle, and in front of the cooler Q3 with a starting'- lrandleQt.

From the foregoing' it will be seen that the engine-frame Vforms a partof the vehicleframe, strengthening the same transversely, and that thevehicle-frame coinbineswith the engine-frame in such a manner that theSide bars of the vehicle-'frame serve to brace the engine-'frame endwiseof the latter.

r[he dashboard or dasher olf the vehicle is made hollow, so astio formaninclosed chamber said chamber being' pi'efei'ably formed by pei'- manentfront, top, and sides, bi'it having an opening at ite rear, or on theside thereof toy the .said pump by pipes iti.

ward the driver of the vehicle, a transparent doorQT, throughwhichtheparts located in the I chamber of the dasher may be observed and whichmay be readily opened Yfor access to the dasher-chamber. The partsinclosed within the dasher-sinice are well protected from the weatherand dust. The engine-shaft is provided at its forward end with aworn'i-whecl meshing with a worin-wheel 2l) on a vertical shaft $30,which extends upward into tliedasherchamber, where it is provided with aSecond worin-wheel 3l, meshing with a worm gearwheel 32, which drivesthe sparker 33, said a centrifugal `governor ifi. lYiLhin thedasherchamber may be located gages to `show water, oil, or g'asolenelevels, as also a sight-'feedv oilpuinp and other parts, all of whichmay be readily observed by t-he driver through the glass door of thedasher. Also within the .lasher-chamber is preferably located the cai'-bin'eter bzlhaving an air-inlet pipe 36, provided with a funnel 3T, andwhich carbureter is supplied with g'asolene or other liquid hydrocarbonfrom a gasolene-tank 35S, connected by a pipe 3S) with a reservoir it),suitably connected with the carbureter. lilith the egress or outlet pipeof the carbureter are connected suitable pipes l to convey gaseous` fuelto the engine. A centrifugal pump 4t2, located at the lower end of anddriven from the vertical shaft 3l), is provided for the purpose ofkeeping' up a proper circulation of water, said pump being connectedwith the cooler by a pipe -t' and the watei' from the cooler being'caused to return to the jackets of the engine-cylii'iders through pipesil and 415, forming part of the water-circulating system, thewateriaclii-its of the engine-cylinders being connected with lVe do not,however, herein claim this feature of the inclosed dashboard or dasherandthe other features mounted thereon inclosed therein or direct-lycooperating therewith, as this pai't of our invention claimed in ourapplication, Serial No. QUA-(St), lilcd July t3, i90-t, as adivision ofthis application.

The invention is not to be understood as being' limited to the detailsIof construction herein shown and described, as these may be variedwidely without departing from the spirit of the invention.

Having thusl described our invention, we claim and desire to secure byLetters Patentl, ln an automobile, the combination with a vehicle-framecomprisingside bai's, of an opposed-cyl]nder-engine frame ari'ang'edtransversely to the viihicle-framc, and hung by its cylinder portions?from the under sides of thc said side bars, thereby bracing the vehicle-Qb', in which are convenientlylocated many of l the neceasary parts ofthc motor-veliicle, the

frame transversely and so mounting the engine as to give it a low centerof gravity.
